WasThatTrue

Fact-check YouTube claims without leaving the video. Source-backed verdict in one click.

Stop wondering if what you just heard is true. WasThatTrue adds a Fact-check button to the YouTube player. Click it on a claim that sounds off, and the extension pulls the exact quote from the transcript, checks it against live web sources, and shows you the verdict in seconds. You never leave the video. How it works Watch any YouTube video with captions. Click the Fact-check button on the player. Pick the claim you want checked from a list of up to five. Read the verdict, with sources, dates, and a short explanation. Four verdict types, not two TRUE: the claim holds up against the evidence. FALSE: the claim contradicts what reliable sources say. CONTESTED: the evidence is mixed and the answer depends on context. You see the trade-offs, not a forced binary. UNVERIFIABLE: there's no primary source either way. You decide what to make of it. Most fact-checkers force every claim into True or False. Real life isn't always like that, and WasThatTrue says so. Free 3 fact-checks per day Full source-backed verdicts All four verdict types No credit card. Ever. Pro Unlimited fact-checks $5.99/month or $59.99/year Cancel anytime See wasthattrue.com/pricing. Privacy WasThatTrue only runs when you press the Fact-check button. It does not watch your YouTube activity in the background. Each fact-check leaves a short operational record (video ID, a one-way hash of the claim, timing) used for usage counting. The verdict text and raw claim are not stored.

Built for serious viewers who want to think for themselves.
